摘要:
利用高德地图公开的公园兴趣点数据、天地图在线影像以及淮安市第七次人口普查数据，使用平均最近邻指数、标准差椭圆分析法、地理集中指数和网格化的高斯两步移动搜索法等多种方法研究淮安市绿地空间的分布、变化趋势，并对可达性进行评价。通过卫星影像解译提取研究区绿地面积，发现淮安市绿地数量上以小型点状绿地为主、面积上呈现以大型点状绿地占主导的分布格局；研究区绿地呈聚集态势；绿地呈现东北-西南方向的分布；各区的绿地分布不平衡，呈现集中特征；可达性是以公园绿地为中心，具有明显的“圈层式”分布特征，高值区出现在中间区域，即主城区，可达性范围在0—1 303.56之间，仍有较高水平。认为淮安市绿地分布呈现明显的聚集特征，分布不均衡，且具有较高的可达性。
Abstract:
Using the data of park interest points published by AmAP,the online images provided by NGCC and the 7th population census data of Huai’an City, the distribution and change trend of green space in Huai’an City were studied by means of average nearest neighbor index,standard deviation ellipse analysis method,geographical concentration index and grid-based Gauss two-step mobile search method,and an evaluation of accessibility was made. Based on the greenbelt area of the study area extracted through satellite image interpretation, it was found that the greenland of Huai’an City was dominated by small dotted ones in quantity, but by large dotted greenbelts in area. Green space was clustered in the study area. The distribution of green space in each district was unbalanced and showed the characteristics of concentration. The accessibility was centered on the green space of the park and had obvious “circle type” distribution characteristics.The high value area appeared in the middle area, i.e. the main urban area,and the accessibility range was 0—1 303.56, still at a high level.To sum up,the distribution of green space in Huai’an City shows obvious of characteristics aggregation,unbalance and high accessibility.
